The prophylactic effect of corn supplementation on experimental nitrate intoxication in cattle.
Sodium nitrate was administered through rumen cannulae to produce NO-3 intoxication in four cows (382 to 445 kg body wt) fed prairie grass hay and a protein-mineral supplement. The cows were fed 0, 1.6 or 3.2 kg of dry rolled corn daily for 10 d prior to sodium nitrate administration. Sodium nitrate administration was followed by a marked increase in intraruminal NO-2 and NH3 and blood NO-2 and...
متن کاملA Review of Nitrate and Nitrite Toxicity in Foods
Agricultural advancement and population growth have prompted increases in food supplies, and higher crop yields have been made possible through the application of fertilizers. Large quantities of livestock and poultry on farms, along with the accumulation of biomass and agricultural residues, can cause contamination of ground water resources and other water sanitation concerns in both developin...
متن کاملNitrate intoxication due to ingestion of pigweed red-root (Amaranthus retroflexus) in cattle

متن کاملNitrate and Nitrite Ultraviolet Actinometers
We developed nitrate and nitrite actinometers to determine radiant fluxes from 290 to 410 nm. These actinometers are based on the reaction of the photochemically generated OH radical with benzoic acid to form salicylic acid (SA) and p-hydroxybenzoic acid (pHBA). Actinometer development included determination of the temperature and wavelength dependence of the quantum yield for formation of SA a...
متن کاملNitrate and Nitrite Reduction in Relation
Soybean (Gcine nax L. cv Williams) seeds were sown in pots containing a 1:1 perlite-vermiculite mixture and grown under greenhouse coditions. Nodules were initiated with a nitrate reductase expressing strain of Rhizobiumjaponicwn, USDA 110, or with nitrate reductase nonexpressing mutants (NR108, NR303) derived from USDA 110. Nodules initiated with either type of strain were normal in appearance...
